PORTABLE DEER-IGK.

To all whom it may concern.'

Be it known that I, AnTEMUs N. HADLEX, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Portable Derricks; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters4 and figures of reference marked thereon, which form a part of this specification.

This invention relates to portable derricks of the class that are designed to be moved from place to place on highways or across fields, and to be used either for loading or for unloading, and especially for expeditiously loading corn-shocks ontowa ons, the invention having reference particu arly to various features of construction in a lightweight portable derrick.

The object of the invention is to provide a portable derrick for lifting purposes generally, and especially adapted to be easily moved in fields; another object being to provide a portable derrick that will b-e adapted to assist in operating shock-lifters, and to provide improvements to enable the derrick to be moved from the positions of the shocks to the positions of other shocks in succession and be quickly stopped and put into operation for lifting the shocks: a still further object being to provide improvements whereby the derrick will be enabled to take advantage of the force of gravity in swinging the loads lifted thereby.

Another object is to provide an improved derrick vehicle or carriage that will be of lightweight and strong, not liable to upset or turn over and yet be adapted to be turned at sharp angles while in transit.

The invention consists in an improved portable derrick comprising a wheeled carriage, lifting apparatus mounted on the carriage and including a hoisting cable, an anchor mounted on the carriage and adapted to be dropped into engagement with the ground for stopping the carriage, means for holding the anchor from the ground while moving the carriage, a draft device connected to the hoisting cable and also connected with the means for holding up the anchor to normally draw the carriage, and means for instantly severing connect-ion between the draft device and the anchor.

The invention consists also in novel fea- Spcccation of Letters Patent.

Similar reference characters throughoutthe drawings indicate corresponding elements or features of construction referred to herein.

The improved portable derrick comprises a supporting and carrying frame formed as a carriage having four wheels for its transportation, and the axles of the carriage form parts of the frame. Preferably a hollow forward axle main part 1 is employed having preferably a bearing-plate l on tie top thereof, the ends of the part 1 having end pieces 2 and 2 thereon, the end pieces having hinge-jaws 3 and 3 formed thereon in which are vertical hinge-pins 4 and 4 to which are connected axle ends 5 and 5, being thus adapted for the forward axle and the forward wheels 6 and 6 are mounted rotatively on the pivoted axle ends, the axle Vjections 14 and 14.

ends being provided with controlling arms 7 and 7 respectively to which a couplingbar 8 is connected by pivots 9 and 9, the middle portion of the bar having a yoke 3 on the top thereof. Each end piece 2 and 2 has a recess 10 therein in which is a bearingplate 11 that is engaged by screws 12 with which the end piece is provided, thus securing the end piece rigidly to the hollowT main part of the axle. The end pieces have rearward extending projections 13 and 13 and also upwardly extending oblique-angle pro- The rear axle 15 is hollen7 and has the rear wheels 16 and 16 mounted rotatively on its ends, one wheel being kept in position on the axle by suitable collars 17 and 17, and the other wheel is kept in proper position by suitable collars 18 and 13 -on the axle. Two rods 19 and 19 which are preferably hollow are arranged in the axle 15 and form movable parts thereof and assist in stiifening the carriage frame of which the axle is a part, and either one of the rods may suitably be drawn partially out of the end of the axle for purposes to be hereinafter explained. Two collars 2O and 20 embrace the axle 15 and each collar has a bearing-plate 21 therein in contact with the axle and engaged by set screws 22, the collar 20 having also a set-screw 23 fitted therein that extends through the bearing-plate 21 and through the adjacent wall of the axle 15 and bears against the rod 19 for holding the rod in any desired position, and the collar 20 is provided with a similar set-screw 23 for the other rod 19. The collars 20 and 20 have forward projections 24 and 24 and also angular projections 25 and 25 respectively. The under sides of the end pieces 2 and 2 are provided each with an apertured lug 26, and the under sides of the collars 20 and 20 are provided each with a similar apertured lug 26. A pair of frame slide bars 27 and 27 are secured to the projections 13 and 13 and also to the projections 24 and 24.

r1`wo frame posts 28 and 28 are secured to and supported by the projections 14 and 14, two other frame posts 29 and 29 being secured to and supported by the projections 25 and 25, the posts leaning convergently so that their upper ends extend nearly to the middle or vertical axis of the frame, and a suitable collar 30 is secured rigidly to the tops of the posts. The collar haat an upturned flange 30 in the top of which are notches 32. The collar supports and guides an eccentric block 33, the opening in which is relatively large and has an operating lever or handle-bar 34 connected to the top thereof by a pivot 35, the lever being adapted to enter either one of the notches 32 to prevent rotation of the eccentric block on the collar and is adapted also to turn the collar when unlatched. A relatively smaller eccentric block 36 is mounted rotatively in the opening of the eccentric block 33 and the opening therein is central with the collar 3() when both eccentric blocks are set in the positions illustrated in F ig. 3, the smaller eccentric block having a lever or handle-bar 37 connected thereto by a pivot 3S for its operation and adapted to enter either one of the notches 32 to latch the eccentric bloclr 36. A plurality of rods as 39, 39, 39, are hung to the collar 30 and have a center piece 40 connected to the lower ends thereof, the center piece having a concave socket 41 therein in the center of which is an aperture 42. A hollow mast column 43 is provided at its lower end with an annular convex bearing piece 44 that is seated in the socket, so as to form a ball and socket joint, and the column extends through the opening in the smaller eccentric block 36 so that if the eccentric blocks or either one of them be turned rotatively about the column the vertical angularity of the column may be changed with respect to the carriage frame or supporting base of the derricl. Two rods 45 and 45 are connected to the forward portion of the centerpiece and are connected to the lugs of the end pieces 2 and 2 of the forward axle,.two other rods 46 and 46 being connected to the rear part of the center-piece 40 and are connected also to the lugs of the collars 20 and 20 respectively, thus bracing the frame and maintaining-the center piece 40 in its proper central position. The ends of the rods that are connected to the center-piece are slightly higher' than the opposite ends of the rods so that the rods have a tendency to draw the center-piece 40 downward, so that as the strains are resisted by the frame posts the whole frame is stiffened and the centerpiece 40 cannot jolt upward during movements of the carriage over rough ground. The center-piece 40 has two side-plates 47 and 47 between the lower portions of which a sheave 48 is mounted rotatively.

It will be understood from the foregoing that the column 43 is rotatively supported, and the mast may have any suitable lifting apparatus mounted on the top thereof, but as adapted for lifting loads to moderate heights the column extends but a short dis tance above t-he top of the eccentric block 36 and it has a head 49 mounted thereon and preferably secured thereto in any suitable manner, but it is obvious that if desired the column 43 may support the head 49 rotatively. The head 49 has a laterally extending arm 50 on one side thereof and also two hinging ears 51 and 51 on the opposite side thereof that have a hinge-rod 52 mounted therein.

The mast of the derrick comprisesA also a base member 53 that normally rests on the arm 50 and has two hinging arms 54 and 54 connected to the hinge-rod 52. A bracket 55 is suitably supported by the head 19 and has a guide-sheave 5G mounted therein, the bracket having a guide 57 extending opposite to the sheave, so as to guide a cable centrally in the mast. Two mast posts 58 and 58 are mounted on opposite end portions of the hinge-rod 52 and converge at their upper ends between which a sheave 59 is mounted on a shaft 60 that is connected to the upper ends of the posts. r1`wo staybars 61 and G1 are connected to the shaft G0 and extend to the end of the base-member 53 farthest from the hinge-rod 52 and are secured by a bolt or rivet 62 to opposite sides of the base-member. The stay-bars have curved extensions 63 and 63 extending downward against and beyond the sides of the arm 50 and have apertures Get therein to receive a pin or bolt G5 wheieby the exten sions are connected to the arm 50 so that the base member 53 is secured against movement on its hinge. After removing the pin or bolt 65, base member 53 may then be moved on its hinge and held at any desired position by inserting the pin or bolt into others of the apertures 64k. A beam 6G forming part of an arm extends from the upper ends of the posts 58 and 58, being preferably connected thereto by the shaft 60, and the outer end thereof has a pair of braces 67 and G7 connected thereto by a housing 68 in which a sheave 69 is mounted, the braces being connected to the hinge-rod 52 for support. The arm has suitable reach laterally and as to height to suit requirements and is approximately balanced by means of a beam 7() that is connected by a bolt or rivet 71 to the lower ends of the extensions 63 and 63 and extends horizontally rearward or opposite to the direction of the arm of t-he derrick, the outer end of the beam having a cross-bar 72 mounted thereon to which a stay-rod 73 is connected, the stay-rod being connected also to the upper ends of the posts 58 and 58 preferably by means of the shaft 60. Preferably two stay-rods 711 and 74 are connected also to the cross-bar 72 and to the hinge-rod 52, and also two other stay-rods 7 5 and 75 connected to the beam and to the hinge-rod 52. Two collars 76 and 7 6 are secured adjustably to the beam 70 by set-screws 77 and 77 respectively or by other suit-able means, and a suitable number of weights 78 are arranged on the beam 70 between the collars, so that the weights may be adjusted as may be desired to the best advantage in operation.

A draw bar is connected to the center piece 40 and it preferably comprises two bars 79 and 79 suitably connected together with space between them and having a hinge-jaw 80 attached thereto that is con` nected by a vertical pivot 81 to a hingeblock 82 which is attached to the plates L.t7 and 47 of the center piece by a bolt 83. The draw-bar extends across and is supported at its forward end portion on the axle part 1, normally resting on the bearing plate 1, and the forward end of the drawbar is provided on the under side thereof with a projecting guide plate 84, the end portion of the draw-bar extending through the yoke 8 and thereby assisting to support the coupling-bar 8; and it will be seen that when the draw-bar swings in a horizontal plane about its pivot 81 it will move the coupling-bar 8 and consequently move and control the arms 7 and 7 so that the carriage may be guided in its movements by means of the draw-bar. A guide-sheave 85 is mounted between the bars forming the draw-bar at a suitable distance from the forward or outer end thereof.

The anchor comprises a beam, which is preferably formed of two bars 8G and 8G spaced apart and suitably connected together, and provided with a hinge-jaw 87 that is connected by a vertical pivot 88 to a hinge-block 89 which is connected to the plates 4:7 and a7 below the hinge-block 82 by a suitable pivot 90 that is arranged horizontally, so that the beam may swing both horizontally and vertically. Two guide arms 91 and 91 are secured to the beam and extend upward at opposite sides of the draw-bar, the tops of the arms being connected by a cross-bar 92 extending above the draw-bar to limit the downward movementof the beam, the arms being connected also by a cross-bar 92 arranged below the draw-bar to limit the upward movement of the beam with respect to the draw-bar, the cross-bar 92 being adapted to engage the under side of the draw-bar to prei-ent the beam of the anchor from binding against the under side of the axle part 1. The anchor beam is provided with a suitable main head member 93 which is provided at the lower end thereof with hinges 94 to which a movable head member 95 is attached and thereby connected to the main head part 93. The hinge member 95 extends downward forwardly with respect to the anchor beam and has Fingers 95 on the forward edges thereof adapted to be forced into the ground when the anchor is dropped. The member 95 is suitably constructed so that it cannot swing upward beyond its normal position, but may swing downward in order to withdraw the fingers readily from the ground, and it is held in proper position to be forced into the ground by means of a knuckle-bar comprising a rod 97 that is connected to the under side of the member 95 by a pivot 98 and connected by a hinge-pin 99 to a rod 100 that is connected by a pivot 101 to the anchor beam, the pivot 99 being below the plane of the rods 97 and 100, the adjacent ends of the rods abutting when the rods are in alinement so that the knuckle-bar may break upward, but not downward, the knuckle-bar being normally held so as to be straight by a spring 102 secured to a bearing-block 103 that is attached to the anchor beam and pressing on the top of the rod 97. A loop 104 is connected to the hinge-pin 99 and has a cable 105 connected thereto that extends over the sheave 85 and under the yoke 8 and has a loop 106 formed on the end thereof which rests on the guideplate 84 when the anchor is down to the ground. A yoke 107 is mounted on the an- Chor-beam to be engaged by the rod 100 of the knuckle-bar so that when drawing the cable 105 forward the anchor may be lifted by means of the knuckle-bar; or other equivalent devices may be employed to obtain the same result. A suitable latch equipped knuckle-jointed cast-off hook 108 is provided to be connected to the loop 106 and has a draft cable or chain 109 connected thereto that is suitably connected to a draft device 110, the latch of the cast-off hook being operated by a rope 111 to be manipulated by the operator of the machine or the driver of the draft team. Any suitable power, of course, may be connected with the draft device 110. A hoisting cable 112 is connected to the draft device 110 and extends through a guide 8 that is carried by the coupling-bar 8 and thence rearward be-A tween the two bars of the anchor beam to and about the guide-sheave 48, thence extending up through the hollow mast column 43 between the sheave 56 and the guide 57 to and over the sheave 59 and thence over the sheave 69, and is adapted to lift either by direct connection with shock lifters or other articles, or the cable may be connected with a pulley-block 113 and have the end portion 114 thereof carried up and attached to the end of the arm near the sheave 69. The axle 15 has a loop 115 thereon to which the pulley-block or the end of the cable may be connected to prevent the arm from swinging when not in use and when being moved from place to place.

A shock lifter described in Letters Patent No. 886,123, granted to me April 28, 1908, is indicated by broken lines in Fig. 12 to illustrate one of the uses of the rods 19 and 19 and the functions thereof, the patented apparatus comprising a head 116 to which are connected prongs 117 that are adapted to be forced into a standing shock of corn, curved arms 118 and 118 being provided to embrace the sides of the shock and hold it upright while being lifted, and the shock lifter and its load is controlled by an operating handle 119 extending from the head 116, the handle having a suitable device 120 thereon such as a swinging arm or finger adapted to be engaged by the rod 19 when ,drawn out or by the other rod 19 if drawn out of the axle when the shock lifter is used at the opposite side of the derrick. The shock lifter having been fully described in the Letters Patent therefore needs no further description.

Usually a beam 121 is attached to the posts 28 and 28 and a drivers seat 122 is mounted on the beam. A pair of brackets 123 and 123 are attached to the rear sides of the posts 29 and 29 for carrying various implements that may be used with the derrick from place to place, as for instance the shock lifter may rest on the brackets with the operat-ing handle thereof extending rearward and supported by the hoisting cable, or a hay rake and lifter of somewhat similar construction to that of the shock lifter may be carried in a similar manner.

It should be understood that the frame of the carriage may be provided with any suitable platform or platforms for the use of attendants, but are omitted in the drawings in order to avoid obscuring more important parts of the machine. It should be understood also that various modifications are contemplated within the scope of the claims as circumstances may indicate.

It will be apparent that in lieu of the well known cast-olf hook, any equivalentdevice may be employ-ed that may be adapted to connect the cable or chain 109 with the cable 105 for draft purposes and so that they may be instantly disconnected by means of a pull-cord while under pulling strains. It should be understood that the crook of the hook 108 is hinged and normally latched to the shank portion thereof, and may be released to swing open so as to be drawn by the cable 109 out of the loop 106, when the latch is retracted by the cord 111.

Then moving the derrick the draft device will draw the cable 105 forward slightly and thereby raise the anchor and then draw the carriage forward until it arrives at the required place for lifting a shock, the suspended shock lifter then being prevented from swinging rearward and forced into engagement with the shock when the deviceV 120 is engaged by the rod 19 or 19, and then the attendant will jerk the rope 111 and thereby disconnect the cast-off hook 108 from the loop 106 so that the -pulling stress will be transferred from the cable 105 to the hoist-ing cable 112 and permitting the anchor to drop to the ground and instantly stop the carriage while the hoisting operations proceed without delay. While moving the derrick toward a shock the levers 34 and 37 may require to be operated so as to readjust the vertical angle of the mast column 43, it being desired that the mast lean slightly so that the arm of the derrick will be affected by the force of gravity to swing the load from the place at which it may be piclred up to the place at which the load is to be deposited, or in some cases it may be desired that the arm shall swing in the opposite direction by the force of gravity, and in attaining this result the weights may be required to be increased or decreased or shifted on the beam 70, as will be understood. 1t will be understood that when the eccentric block 33 is rotated and the eccentric-block 36 does not turn in vthe eccentric-block 33 there would be no change of angularity of the mast, butv this will determine the direction toward which the mast may lean when the eccentric-block 36 is turned in the larger eccentric-block 33. 1When moving the derrich from place to place it is preferred to lower the arm as in ,F ig. 1 in order to clear bridge roofs or other overhead work, and when the arm is so adjusted it is preferable to shift the weights 78 toward the inner end of the beam 70.
